2015 Toyota Auris — MOT failures & pass rate
The 2015 Toyota Auris passed 88.5% of its 98,529 recorded MOT tests. Against small family cars of a similar age (15.6% fail rate), the 2015 Auris comes out 4.1pp better. Failures cluster in lighting & signalling, tyres and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (7.9%) and tyres (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp, headlamp aim and wipers — headlamp alone was recorded 3,371 times.
Mileage is the strongest signal on the record: 5.6% of 0-30k cars fail, rising to 16.0% once past 150k — 2.8× the risk.
The petrol cars hold up better: 10.4% fail against 14.2% for diesel, a 3.8-point gap across 36,633 tests.
Tyres is the most common advisory, noted on 20.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.1% of tests failed in 2021 against 13.8% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Auris
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 7.9% of tests. Start there.
- Lighting & signalling (7.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Brakes (3.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
